The teachers would have to be screened and trained, no doubt. Another answer could be more cops in schools. I don't know what the answer is, and I 'm sot sure that anyone does. All I know is that protecting children is the most important thing. I do so in my own ways. I can get physical if the need calls for it (I was an M.P. in the Marine Corps, I've worked in a county jail, and I've worked in security), but I can also shoot really well.
